问题 Normally i get the data from a webpage but i want to send it from the command line to facilitate debugging. To get the data i do something like: my $query = new CGI; my $username = $query->param("the_username"); this doesn't seem to work: $ ./script.pl the_username=user1 EDIT: Actually the above works.

问题 I am documenting a codebase using Doxygen and was wondering if there is a keyword for declaring an argument to a function to be optional. Something like: /*! \fn int add(int a, int b=0) \brief adds two values \param a the first operand \param \optional b the second operand.
